Influence of Seed Invigoration with Organic Kunapajala on Seed Quality and Biochemical Activity in Late Sown Wheat

A laboratory experiment was conducted at GBPUA&T, Pantnagar during rabi season of 2020-2021 to study the influence of seed invigoration with organic kunapajala on germination and biochemical activity in wheat variety UP-2526. The experiment was laid in completely randomized design which consisted of five treatments viz; no seed priming (control), Hydropriming for 16 hours, kunapajala seed priming @10%, 25% and 50% for 16 hours. Results revealed that germination percentage in hydro primed seeds and 25% kunapajala primed seeds jointly recorded maximum germination percentage (99.7%) which was statistically at par with 10% kunapajala priming (99.3%). Seed reserve mobilization efficiency after 4th day and 8th day of incubation was significantly affected by seed invigoration treatments. 25% kunapajala primed seeds recorded significantly higher dehydrogenase activity (0.68 OD) which was at par with hydroprimed seeds and 10% kunapajala primed seeds (0.63 and 0.62 OD, respectively). So, seed priming with either 10% or 25% organic kunapajala is an effective method to bring about improvement in germination of wheat and predict its field performance.
